Example: class MyFirstJavaClass Method Names All method names should start with a Lower Case letter. If several words are used to form a name of the class, each inner word's first letter should be in Upper Case. Class Names For all class names the first letter should be in Upper Case. Case Sensitivity Java is case sensitive, which means identifier Hello and hello would have different meaning in Java. About Java programs, it is very important to keep in mind the following points. You will be able to see ' Hello World ' printed on the window.
Now, type ' java MyFirstJavaProgram ' to run your program. If there are no errors in your code, the command prompt will take you to the next line (Assumption : The path variable is set). Type 'javac MyFirstJavaProgram.java' and press enter to compile your code. Open a command prompt window and go to the directory where you saved the class.

public class MyFirstJavaProgram Say Helloĥ 5 Display my favorites and my perfromance by using methods Let's look at how to save the file, compile, and run the program. Let us look at a simple code that will print the words Hello World. An object's state is created by the values assigned to these instance variables. Instance Variables Each object has its unique set of instance variables. It is in methods where the logics are written, data is manipulated and all the actions are executed. Methods A method is basically a behavior. Class A class can be defined as a template/blueprint that describes the behavior/state that the object of its type supports. Example: A dog has states - color, name, breed as well as behavior such as wagging their tail, barking, eating. Object Objects have states and behaviors.
Let us now briefly look into what do class, object, methods, and instance variables mean. Write once, run anywhere BASIC SYNTAX When we consider a Java program, it can be defined as a collection of objects that communicate via invoking each other's methods. Java development is not only focused on one operating system, but is developed for a variety of operating systems and is open source. Java programming language is object oriented (OOP-Object Oriented Programming), and can run on various operating systems. 64ģ 6.2.3 BINARY TREE ABSTRACT DATA TYPE LINKED STRUCTURE FOR BINARY TREE BINARY SEARCH TREE RED-BLACK TREE EXERCISE HOMEWORK LEARNING OBJECTIVES MATERIALS Hash Function Preventing Collision Exercise LEARNING OBJECTIVES MATERIALS OVERVIEW Array Implementation Heap insert Heap remove Print the heap tree Exercise Homework LEARNING OBJECTIVES MATERIALS OVERVIEW GRAPH IMPLEMENTATION EXERCISES LEARNING OBJECTIVES MATERIALS WEIGHTED GRAPH OVERVIEW WEIGHTED GRAPH IMPLEMENTATION EXERCISES HOMEWORKĤ 4 CHAPTER 1 INTRODUCTION TO JAVA 1.1 LEARNING OBJECTIVES 1 Students began to recognize the Java Programming 2 Students can use the Java language to create programs 3 Students understand the terms on Java 1.2 MATERIALS Java is a programming language that can make all forms of application, desktop, web, mobile and other, as made by using conventional programming language to another. 5.1 OBJECTIVES MATERIALS MERGE-SORT OVERVIEW EXERCISES LEARNING OBJECTIVES MATERIALS TREE OVERVIEW BINARY TREE.
